Infrared (IR) — Sensor and Solenoid Valve Troubleshooting

If a station is not functioning properly it is most likely either the solenoid valve or the sensor.Troubleshooting multi station units is fairly easy, as you can swap parts (actually just by changing the wires)and use the process of elimination to figure out which of the 2 parts is causing the problem.

How the system operates:1. The transformer sends 24 volts to the sensor. 2. The sensor acts only as a switch. 3. When hands go into the active field of the sensor, the sensor activates and sends a power signal

on to the solenoid valve.4. The power signal activates and opens the solenoid valve which allows the water to flow to the

sprayhead. The solenoid valve stays open allowing water to flow as long as it is receiving a signal form the sensor (hands remain in the active field).

5. When hands are removed from the active field, the sensor turns off (note some models have a slight delay feature built-in.) and shuts off the power signal to the solenoid valve.

CAUTION: Turn off water supplies to unit before troubleshooting.Problem: An individual operating station fails to shut off and drips.Cause: There is debris trapped between the diaphragm and the valve seat.Solution: Remove debris between diaphragm and the valve seat.

1. Remove the three #8 Phillips-head screws that hold the solenoid valve assembly together. Becareful not to lose the armature or spring.

2. Remove the diaphragm. Remove any particles that have been trapped between the diaphragmand the valve seat. Rinse off the diaphragm and inspect for damage. Make sure the center ori-fice and both small side orifices are open.

3. Reassemble in reverse order, being careful not to overtighten the Phillips-head screws or youmay crack the plastic valve body. Tighten until the armature plate makes contact with the plasticbody.

4. Reconnect the wiring per the appropriate diagram on next 4 pages.Problem: An individual operating station fails to turn on.Cause: A failed coil for the valve or loose electrical connection to the terminal.Solution: Test the station to determine cause.1. Disconnect the wires from the coil of an adjacent valve. Disconnect the wires from the problem

valve and reconnect to the adjacent valve.2. Turn on electrical and water supplies to the unit. Pass your hand in front of the sensor of the

problem station, and the adjacent station should turn on. If the adjacent station turns on and cycles normally, replace the coil on the problem valve.If the adjacent valve fails to turn on, inspect the wires from the sensor cable and do the following:• make sure there are no breaks and that the fully insulated disconnect terminals are firmly

crimped in place;• turn off the electrical and water supplies;• reconnect to the adjacent valve and turn on the water supplies to the unit;• pass your hand in front of the sensor. If the station still fails to turn on, replace the sensor.

Troubleshooting Air Valve Metering Hand Control (AST4)CAUTION: Turn off water supplies to unit before troubleshooting.

Problem: One or more individual operating stations fail to turn on.Cause: Incoming water pressure is over 80 PSIG.Solution: Reduce water pressure to below 80 PSIG.

Install a pressure-reducing valve at the building main set to the manufacturer's recommendations.Lower line pressure will improve the performance and extend the life of all the plumbing in thebuilding.

Problem: An individual operating station fails to turn on.Cause: A failed diaphragm/magnet assembly.Solution: Test the station to determine cause.

1. Unscrew the valve clamp nut on the top of the valve (see Page 25).2. Remove valve cover. If the diaphragm/magnet assembly comes out with the cover, gently peel

the diaphragm away form the cover, taking care not to damage the diaphragm. Inspect thediaphragm for any holes of tears. A damaged diaphragm needs to be replaced.

3. Insert the diaphragm/magnet assembly back into the valve, but leave the cover off.4. Gently press the diaphragm until it is fully depressed. The valve should activate. If not, the

diaphragm/magnet assembly needs to be replaced.

Problem: One or more individual operating stations turn off too quickly or run too long.Cause: Timing requires adjustment.Solution: Readjust timing (see Page 24).

Problem: An individual operating station cannot be adjusted to run for more than five seconds.

Cause: Air tube connection leak.Solution: Check 1/8" tubing connection.

1. Tighten compression nut at 1/8" tubing connection to air valve in pedestal.2. If leak persists, remove the sprayhead cover and check the 1/8" elbow tube connection behind

the pushbutton assembly. Make sure the screw holding the elbow is tight and the fitting in theelbow is firmly hand tightened. Make sure the tubing is pushed firmly into the fitting.

3. If leak persists, reseat the 1/8" tubing. Disconnect the tubing from the fitting by pressing downon the plastic ring at the top of the fitting while firmly pulling the tubing out of the fitting. Trim½" off the end of the tubing squarely with a razor-sharp knife and push the tubing firmly backinto the connector to make sure it is seated.

4. If the leak still persists, loosen the compression nut on the air valve inside the pedestal and pullthe tubing out of the fitting. Trim ½" off the end of the tubing squarely, with a razor-sharp knife.Then slide the tubing through the nut until ½" of tubing is exposed. Insert tubing into the com-pression fitting on the valve body and hand tighten the compression nut.



Troubleshooting Air Valve Metering Hand Control (AST4) ....Continued

Problem: An individual operating station won't turn off and drips.Cause: There is debris trapped between the diaphragm and valve seat.Solution: Remove debris between the diaphragm and valve seat.

1. Remove the three Phillips-head screws that hold the air valve together. Be careful not to lose thearmature or spring (see Page 25).

2. Remove the diaphragm. Remove any debris trapped between the diaphragm and the valve seat.3. Rinse off the diaphragm and inspect for damage. Make sure the center orifice and the two small

side orifices are open.4. Reassemble in reverse order, being careful not to over tightening the Phillips-head screws or you

may crack the plastic valve body. Tighten until the armature plate makes contact with the plasticbody.

Problem: An individual station will not shut off.Cause: Timing mechanism is clogged.Solution: Clear the timing mechanism.

1. If the timer cover has been sprayed with water, wait at least two minutes. It will shut off andreturn to normal operation once it dries off.

2. If it doesn't turn off remove the timer cover. If the valve shuts off the cover is clogged andneeds to be replaced.

3. If the valve still doesn't turn off, turn the adjusting screw counter clockwise until it can beremoved from the valve body.

4. Wipe adjusting screw thoroughly with a lint-free towel making sure that there is no water ordebris on the adjusting screw.

5. Use a pipe stem cleaner to wipe the inside of the timer body if possible.6. Replace timer-screw and adjust valve timing.7. Replace timer cover.



Troubleshooting Air Valve Hold-Open Foot Control (AST4-F)Problem: One or more individual operating stations fail to turn on.Cause: Incoming water pressure is over 80 PSIG.Solution: Reduce water pressure to below 80 PSIG.

Install a pressure-reducing valve at the building main set to the manufacturer's recommendations.Lower line pressure will improve the performance and extend the life of all the plumbing in the build-ing.

Problem: An individual operating station turns off while the foot button is depressed.Cause: Air tube connection leak.Solution: Check 1/8" tubing connection.1. Tighten compression nut at 1/8" tubing connection to air valve in pedestal.2. If leak persists, remove the two screws securing the foot button escutcheon and check the 1/8"

elbow tube connection behind the pushbutton assembly. Make sure the screw holding the elbowis tight and the fitting in the elbow is firmly hand tightened. Make sure the tubing is pushedfirmly into the fitting.

3. If leak persists, reseat the 1/8" tubing. Disconnect the tubing from the fitting by pressing downon the plastic ring at the top of the fitting while firmly pulling the tubing out of the fitting. Trim½" off the end of the tubing squarely with a razor-sharp knife and push the tubing firmly backinto the connector to make it is seated.

4. If the leak still persists, loosen the compression nut on the air valve inside the pedestal and pullthe tubing out of the fitting. Trim ½" off the end of the tubing squarely, with a razor-sharp knife.Then slide the tubing through the nut until ½" of tubing is exposed. Insert tubing into the com-pression fitting on the valve body and hand tighten the compression nut.

Problem: An individual operating station fails to turn on.Cause: A failed diaphragm/magnet assembly.Solution: Test the station to determine cause.

1. Unscrew the valve clamp nut on the top of the valve. (See Page 25).2. Remove valve cover. If the diaphragm/magnet assembly comes out with the cover, gently peel

the diaphragm away form the cover, taking care not to damage the diaphragm. Inspect thediaphragm for any holes of tears. A damaged diaphragm needs to be replaced.

3. Insert the diaphragm/magnet assembly back into the valve, but leave the cover off.4. Gently press the diaphragm until it is fully depressed. The valve should activate. If not, the

diaphragm/magnet assembly needs to be replaced.



Vernatherm™ Thermostatic Mixing Valve TroubleshootingNOTE: Before attempting to troubleshoot the valve or disassemble the components, check for the fol-lowing conditions:

• If stop/check valves are used, make sure that they are fully open.• Make sure that the hot and cold inlet pipes are connected properly, and that there are no cross-

connections or leaking stop/check valves.• Check the hot water heater output to make sure that it is at least 20° F above the set tempera-

ture.Be sure to close the appropriate shut-off valves prior to disassembly of the valve and reopen thevalves after inspection and repair is complete.

Problem: Limited water flowCause: Dirt and debris have built up in the valve or strainer.

1. Remove and clean strainer (see Figures on next page). If strainer needs to be replaced, orderBradley part no. 173-028.

2. Check the piston for smooth movement.To check the valve's piston for free and smooth movement, follow the procedures outlined below:

1. Remove the valve's cap and thermostat (see next Page ).2. Push down on the piston with your finger (the piston should move freely). If the movement is

not as it should be, the piston needs to be cleaned. Follow the method outlined below for clean-ing the piston and valve body:• Remove the thermostat.• Lift the piston out with a needle-nose pliers and remove the spring.• Any cleaner suitable for brass and stainless steel may be used (if cleaning with suitable cleaner

is not sufficient to remove debris, a 400-grit sandpaper may be used to polish and hone the pis-ton and valve body).

• Snap spring into piston (will detent) and reassemble into the valve body. Retest the piston.3. If, after a thorough cleaning, the piston does not move freely, the piston must be replaced.

Contact your Bradley representative and ask for Repair Kit (part number S65-259).

Problem: External leaks in the systemCause: O-rings have been damaged.

Solution: Replace O-rings where necessary. For replacement of the O-rings, contact your Bradley representative and ask for Repair Kit (part number S65-259).

Problem: Improper water temperature or temperature fluctuationCause: Thermostat is slowly failing or not working at all.

Solution: Check the thermostat for proper operation.1. At room temperature (80° F or less) remove cap and thermostat.2. Place thermostat into container with 115° F water. The pushrod should pop out of the

thermostat approximately 1/10".3. If thermostat pushrod does not pop out, the thermostat must be replaced. Contact your Bradley

representative and ask for Repair Kit (part number S65-259).Cause: Valve temperature is not properly set.

Solution: Adjust the temperature. Using a blade screwdriver, turn the adjustment stem counterclock-wise to increase the temperature or clockwise to decrease the temperature.

Check Valve Troubleshooting InstructionsIf water just dribbles or does not flow from sprayhead:

1. Close stop/check valves that supply water to the washfountain.2 Inspect stop/check valves for proper installation.3. Remove flexible hoses at stop/check valves and clean the strainers if necessary.

If water sprayhead delivers all hot or cold water:1. Close stop/check valves that supply water to the washfountain.2. Inspect stop/check valves for proper installation.3. Remove flexible hoses at stop/check valves and clean the strainers if necessary.4. Inspect mixing valve for proper installation.

• Hot inlet is marked with an”H”.

Care and Cleaning of Stainless Steel Sentry WashfountainsStainless steel is extremely durable, and maintenance is simple and inexpensive. Proper care, particu-larly under corrosive conditions, is essential. Follow the cleaning instructions listed below:

• Ordinary deposits of dirt and grease are quickly removed with soap and water. Whenever pos-sible, the metal should be thoroughly rinsed and dried after washing. To remove tightly adher-ing deposits, use stainless steel polishing powder. In all cases, rub in the direction of the stain-less steel grain.

IMPORTANT: Never use ordinary steel wool or steel brushes on stainless steel. Always usestainless steel wool or stainless steel brushes.

• Avoid prolonged contact with chlorides, bromides, thiocyanates, and iodides on stainless steelequipment, especially if acid conditions exist.

• Do not permit salty solutions to evaporate and dry on stainless steel.• The appearance of rust streaks on stainless steel leads to the belief that the stainless steel is

rusting. Look for the actual source of the rust in some iron or steel particles which may betouching, but not actually a part of the stainless steel structure. NOTE: Strongly acidic orcaustic cleaners may attack the steel causing a reddish film to appear. The use of these clean-ers should be avoided.

SOAP RECOMMENDATIONSQuality soap dispensers require good quality soap and periodic maintenance to properly operate. Bradley soapdispensers will provide dependable, consistent operation over the long term when soap with reasonable viscos-ity and pH levels are used and when a minimal amount of periodic maintenance is performed on the valves.Soap thickness is determined by a measurement called viscosity. Soap viscosity should be between 100 cps(centerpoise) and 2500 cps for all Bradley soap dispensers. Thinner soaps are perceived by the users as being"watered down" so users tend to take more than they need, resulting in waste. Thick soaps flow slower andinhibit the "flushing" action of the valves, which allows the soap to congeal in the valve and cause clogs.The pH (acid) level of the soap should be in the range of 6.5 to 8.5. More acidic soaps (pH levels lower than6.5) will corrode metal parts (even stainless steel!!) and degrade rubber and plastic components. They will alsocause skin irritation. Most inexpensive soaps (typically the pink lotion type) fall into this acidic category andwill eventually cause valve failure and metal corrosion. Base soaps (pH levels higher than 8.5) will causeswelling or degradation of rubber and plastic parts and skin irritation.Generally, any quality soap meeting the viscosity and pH guidelines above will work well with Bradley soapdispensers. PCMX or Isapropanol based antibacterial soaps (within viscosity and pH limits) will also workwith Bradley dispensers. Soaps satisfying these basic guidelines will provide consistent flow and reduce clogs.Most soap dispenser problems are caused by soap that is too thick or corrosive, or by a lack of maintenance.Many soaps come in concentrate form which must be diluted with water. Often, the soap is improperly dilutedor used straight out of the bottle, which causes clogging and valve failure. If proper soap is being used, valvesthat have never been cleaned are usually the source of dispensing problems. Bradley has entered into an agree-ment with Champion Brand Products to provide additional customer service for purchasers of our dispensersregarding soap issues. They are very helpful and can get to the bottom of almost any soap dispenser relatedproblem. They also sell an excellent "Bradley approved" soap. Please see Soap Instruction Sheet 215-1286for details about soap valve cleaning or how to contact Champion. With proper maintenance and soap, Bradleydispensers will provide long term, trouble free operation.

SOAP DISPENSER MAINTENANCE INSTRUCTIONS

Sentry WashfountainsBradley soap dispensers will provide dependable, consistent operation over the long term when the propersoap is used and when a minimal amount of periodic maintenance is performed on the valves. Valves must bemaintained (cleaned) to function properly. To ensure proper operation of your soap dispenser, follow these instructions:• Once per month, remove the cap from the soap tank and insert the draw tube (below the cap) into hot water

and soak it for 30 minutes.• Push valve at least 20 times while it is soaking.• Flush soap reservoir with hot water while valve is soaking.In cases of extreme clogging, the valve should be disassembled and the parts should be soaked in hot water orcleaning solution to restore proper functioning. Soap dispensers that will not be used for extended periods oftime (schools during summer break, etc.) should be drained, cleaned and left empty until put back into service.Soap left on the outside of dispensers can cause discoloration and corrosion of the reservoir (even on stainlesssteel units). All soap should be wiped or scrubbed off daily, then the outside of the dispenser should be rinsedwith clear water and dried with a soft cloth.
